Effect of high doses of ultraviolet radiation on the structure of the reproductive glands of sexually mature male white rats

Ultraviolet (UV) radiation is an important component of sunlight and is widely used in various fields of medicine, cosmetology, and industry. The biological effects of UV radiation are of particular interest due to its ubiquitous presence in the environment, particularly in sunlight, as well as its use in medicine, cosmetics, and industry. It is known that moderate doses of UV radiation have beneficial properties, such as stimulating the synthesis of vitamin D in the skin, improving mood, and boosting immunity. Nevertheless, high doses of UV radiation can cause tissue damage by stimulating the formation of free radicals, leading to photodamage of the skin, eyes, and internal organs. Of particular interest is the potential impact of intense UV radiation on the reproductive system of mammals. Although some studies have been conducted on the effects of excessive UV exposure on various organs and tissues, the impact of high doses of UV on the reproductive system remains understudied, which could potentially affect the ability to reproduce offspring. In our previous research, we found that high doses of ultraviolet radiation had a negative effect on the reproductive function of the male reproductive glands, particularly on the formation of male reproductive cells (sperm). However, the nature of the structural changes that occur in the male gonads themselves remained largely unknown. The conducted experimental study showed that the influence of large doses of ultraviolet radiation has a negative effect on the morphological structure of the male reproductive glands. Special attention should be paid to the fact that the histological specimens showed convoluted seminiferous tubules with no spermatozoa in their lumens. Where spermatozoa were visible, they were more dispersed and in smaller numbers.
